-
FIG. 1 is a view schematically showing construction of an air conditioner according to an embodiment of the present invention. - Referring to
FIG. 1 , theair conditioner 1 according to this embodiment includes acompressor 20 to compress a refrigerant, anoutdoor heat exchanger 170 installed outdoors to perform heat exchange between the refrigerant and outdoor air, anindoor heat exchanger 50 installed indoors to perform heat exchange between the refrigerant and indoor air, aswitching valve 80 to guide the refrigerant discharged from thecompressor 20 to theoutdoor heat exchanger 170 during a cooling operation and to guide the refrigerant discharged from thecompressor 20 to theindoor heat exchanger 50 during a heating operation. - The
air conditioner 1 includes an outdoor unit disposed outdoors and an indoor unit disposed indoors. The outdoor unit and the indoor unit are connected to each other. The outdoor unit includes thecompressor 20, theoutdoor heat exchanger 170, anoutdoor expansion valve 70, and a gas andliquid separator 27. The indoor unit includes theindoor heat exchanger 50 and anindoor expansion valve 60. - The
compressor 20 is installed in the outdoor unit to compress a low-temperature, low-pressure refrigerant, introduced into thecompressor 20, into a high-temperature, high-pressure refrigerant. Thecompressor 20 may be configured to have various structures. Example, thecompressor 20 may be areciprocation type compressor 20 using a cylinder and a piston, ascroll type compressor 20 using a rotatable scroll and a stationary scroll, or aninverter type compressor 20 to adjust a compression rate of the refrigerant based on a real indoor temperature, a real outdoor temperature, and the number of indoor units under operation when a desired indoor temperature is set. One ormore compressors 20 may be provided. In this embodiment, twocompressors 20 are provided. - The
compressor 20 is connected to theswitching valve 80 and the gas andliquid separator 27. Thecompressor 20 includes aninlet port 21, through which a refrigerant evaporated by theindoor heat exchanger 50 is introduced into thecompressor 20 during the cooling operation or a refrigerant evaporated by theoutdoor heat exchanger 170 is introduced into thecompressor 20 during the heating operation, and anoutlet port 23, through which a compressed refrigerant is discharged from thecompressor 20. - The
compressor 20 compresses the refrigerant introduced through theinlet port 21 in a compression compartment. Thecompressor 20 discharges the compressed refrigerant through theoutlet port 23. The refrigerant discharged through theoutlet port 23 flows to theswitching valve 80. - The
switching valve 80 is a flowchannel switching valve 80 for switching between cooling and heating. Theswitching valve 80 guides the refrigerant compressed by thecompressor 20 to theoutdoor heat exchanger 170 during the cooling operation and guides the refrigerant compressed by thecompressor 20 to theindoor heat exchanger 50 during the heating operation. That is, theswitching valve 80 functions to guide the refrigerant compressed by thecompressor 20 to a condenser. - The
switching valve 80 is connected to theoutlet port 23 of thecompressor 20 and the gas andliquid separator 27. In addition, theswitching valve 80 is connected to theindoor heat exchanger 50 and theoutdoor heat exchanger 170. During the cooling operation, theswitching valve 80 connects theoutlet port 23 of thecompressor 20 to theoutdoor heat exchanger 170 and connects theindoor heat exchanger 50 to the gas andliquid separator 27. In another embodiment, however, theswitching valve 80 may connect theindoor heat exchanger 50 to theinlet port 21 of thecompressor 20 during the cooling operation. - During the heating operation, the
switching valve 80 connects theoutlet port 23 of thecompressor 20 to theindoor heat exchanger 50 and connects theoutdoor heat exchanger 170 to the gas andliquid separator 27. In another embodiment, however, theswitching valve 80 may connect theoutdoor heat exchanger 170 to theinlet port 21 of thecompressor 20 during the heating operation. - The
switching valve 80 may be embodied by various modules that are capable of connecting different flow channels to each other. In this embodiment, theswitching valve 80 is a four-way valve. In another embodiment, however, theswitching valve 80 may be embodied by various valves and combinations thereof, such as a combination of two three-way valves. - The
outdoor heat exchanger 170 is disposed in the outdoor unit installed outdoors to perform heat exchange between the refrigerant passing through theoutdoor heat exchanger 170 and outdoor air. During the cooling operation, theoutdoor heat exchanger 170 functions as a condenser to condense the refrigerant. During the heating operation, on the other hand, theoutdoor heat exchanger 170 functions as an evaporator to evaporate the refrigerant. - The
outdoor heat exchanger 170 is connected to theswitching valve 80 and theoutdoor expansion valve 70. During the cooling operation, the refrigerant compressed by thecompressor 20 passes through theoutlet port 23 of thecompressor 20 and theswitching valve 80 and is then introduced into theoutdoor heat exchanger 170, in which the refrigerant is condensed. The condensed refrigerant flows to theoutdoor expansion valve 70. During the heating operation, on the other hand, the refrigerant expanded by theoutdoor expansion valve 70 flows to theoutdoor heat exchanger 170, in which the refrigerant is evaporated. The evaporated refrigerant flows to the switchingvalve 80. - During the cooling operation, the
outdoor expansion valve 70 is fully opened to allow the refrigerant to pass therethrough. During the heating operation, on the other hand, an opening degree of theoutdoor expansion valve 70 is adjusted to expand the refrigerant. Theoutdoor expansion valve 70 is disposed between theoutdoor heat exchanger 170 and aninjection module 90. - During the cooling operation, the
outdoor expansion valve 70 allows the refrigerant introduced from theoutdoor heat exchanger 170 to pass therethrough such that the refrigerant is guided to theinjection module 90. During the heating operation, on the other hand, theoutdoor expansion valve 70 may expand the refrigerant through heat exchange in theinjection module 90 and guide the expanded refrigerant to theoutdoor heat exchanger 170. - The
indoor heat exchanger 50 is disposed in the indoor unit installed indoors to perform heat exchange between the refrigerant passing through theindoor heat exchanger 50 and indoor air. During the cooling operation, theindoor heat exchanger 50 functions as an evaporator to evaporate the refrigerant. During the heating operation, on the other hand, theindoor heat exchanger 50 functions as a condenser to condense the refrigerant. - The
indoor heat exchanger 50 is connected to the switchingvalve 80 and theindoor expansion valve 60. During the cooling operation, the refrigerant expanded by theindoor expansion valve 60 flows to theindoor heat exchanger 50, in which the refrigerant is evaporated. The evaporated refrigerant flows to the switchingvalve 80. During the heating operation, on the other hand, the refrigerant compressed by thecompressor 20 passes through theoutlet port 23 of thecompressor 20 and the switchingvalve 80 and is then introduced into theindoor heat exchanger 50, in which the refrigerant is condensed. The condensed refrigerant flows to theindoor expansion valve 60. - During the cooling operation, an opening degree of the
indoor expansion valve 60 is adjusted to expand the refrigerant. During the heating operation, on the other hand, theindoor expansion valve 60 is fully opened to allow the refrigerant to pass therethrough. Theindoor expansion valve 60 is disposed between theindoor heat exchanger 50 and theinjection module 90. - During the cooling operation, the
indoor expansion valve 60 expands the refrigerant flowing to theindoor heat exchanger 50. During the heating operation, on the other hand, theindoor expansion valve 60 allows the refrigerant introduced from theindoor heat exchanger 50 to pass therethrough such that the refrigerant is guided to theinjection module 90. - The
injection module 90 is disposed between theoutdoor heat exchanger 170 and theindoor heat exchanger 50 to inject a portion of the refrigerant flowing between theoutdoor heat exchanger 170 and theindoor heat exchanger 50 to thecompressor 20. That is, theinjection module 90 may inject a portion of the refrigerant flowing from the condenser to the expansion valve to thecompressor 20. Theinjection module 90 is connected to theoutdoor expansion valve 70 and theindoor expansion valve 60. - The
injection module 90 includes aninjection expansion valve 91 to expand a portion of the refrigerant flowing between theoutdoor heat exchanger 170 and theindoor heat exchanger 50 and aninjection heat exchanger 92 to perform heat exchange between another portion of the refrigerant flowing between theindoor heat exchanger 50 and theoutdoor heat exchanger 170 and the refrigerant expanded by theinjection expansion valve 91. Theinjection heat exchanger 92 guides the heat-exchanged and thus evaporated refrigerant to aninjection port 22 of thecompressor 20. In another embodiment, however, theinjection module 90 may not be included in theair conditioner 1. - The gas and
liquid separator 27 is disposed between the switchingvalve 80 and theinlet port 21 of thecompressor 20. The gas andliquid separator 27 is connected to the switchingvalve 80 and theinlet port 21 of thecompressor 20. The gas andliquid separator 27 separates the refrigerant evaporated by theindoor heat exchanger 50 during the cooling operation or the refrigerant evaporated by theoutdoor heat exchanger 170 during the heating operation into a gas refrigerant and a liquid refrigerant and guides the gas refrigerant to theinlet port 21 of thecompressor 20. That is, the gas andliquid separator 27 separates the refrigerant evaporated by the evaporator into a gas refrigerant and a liquid refrigerant and guides the gas refrigerant to theinlet port 21 of thecompressor 20. - The refrigerant evaporated by the
outdoor heat exchanger 170 or theindoor heat exchanger 50 is introduced into the gas andliquid separator 27 through the switchingvalve 80. Consequently, the gas andliquid separator 27 may be maintained at a temperature of about 0 to 5 °C and cold energy may be dissipated from the gas andliquid separator 27. The surface temperature of the gas andliquid separator 27 is lower than the temperature of the refrigerant condensed by theoutdoor heat exchanger 170 during the cooling operation. The gas andliquid separator 27 may be formed in a cylindrical shape extending in a longitudinal direction. -

FIGS. 4 and5 , theblower apparatus 200 according to the embodiment of the present invention includes ablower fan 220 rotated about a shaft thereof to blow air heat-exchanged with the refrigerant by theoutdoor heat exchanger 170 in one direction and anorifice 210 installed in the case such that the inside and the outside of the case communicate with each other through theorifice 210 to guide the air blown by theblower fan 220. Theorifice 210 includes adischarge part 211 to guide air discharged from the front F to the rear R of theblower apparatus 200 in an axial direction of theblower apparatus 200 by theblower fan 220. The sectional area of thedischarge part 211 is gradually increased from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. - The
blower fan 220 is disposed under thedischarge hole 143 of the outdoor unit body in an upward and downward direction to blow air in the upward and downward direction (from the front F to the rear R of theblower apparatus 200 in the axial direction of the blower apparatus 200). - That is, the
blower fan 220 discharges outdoor air from the outdoor unit body. - The
blower fan 220 blows outdoor air such that theoutdoor heat exchanger 170 performs heat exchange between the outdoor air and the refrigerant. - The
blower fan 220 discharges outdoor air suctioned through the suction holes outward from the case. - In this embodiment, the
blower fan 220 is an axial fan. The axial fan includes ahub 221 rotated by amotor 230 to provide rotational force and blades disposed around thetub 221 in a radial manner at predetermined intervals. - The
hub 221 constitutes a rotational axis of theblades 222. A rotary shaft of themotor 230 is coupled to thehub 221. Thehub 221 may be formed in various shapes. In this embodiment, thetub 221 is formed in a cylindrical shape. - The
blades 222 drive air. A plurality ofblades 222 may be provided around thehub 221. The blades are disposed around thetub 221 in a radial manner at predetermined intervals. Theblades 222 may be formed in the shape of a twisted propeller to rotate air introduced through aninlet port 212 of theorifice 210 and to drive the air in the axial direction of theblower apparatus 200. - Specifically, the
blades 222 are rotated by themotor 230 to drive air from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. - The front F of the
blower apparatus 200 in the axial direction of theblower apparatus 200 may be aligned with a direction of gravity (a downward direction). - The
orifice 210 is installed in the case such that the inside and the outside of the case communicate with each other through theorifice 210 to guide the air blown by theblower fan 220. - Specifically, the
orifice 210 may be located at the upper region of the case such that theorifice 210 communicates with thedischarge hole 143. - The
blower fan 220 is disposed inside theorifice 210. - Specifically, the
orifice 210 may form a closed space to surround theblower fan 220 on a horizontal plane perpendicular to the axial direction of theblower apparatus 200. The axis means a shaft about which theblower fan 220 is rotated. - The internal space of the
orifice 210 may be formed in a shape in which the front F and the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 are opened and theorifice 210 surrounds theblower fan 220 in a direction perpendicular to the axial direction of theblower apparatus 200. That is, theorifice 210 is formed approximately in a cylindrical shape. - The internal space of the
orifice 210 defines a flow channel to guide air blown by theblower fan 220. Aninlet port 212, through which air is introduced by theblower fan 220, is formed in internal space of theorifice 210 at the front F of theblower apparatus 200 in the axial direction of theblower apparatus 200 and anoutlet port 214, through which air is discharged by theblower fan 220, is formed in the internal space of theorifice 210 at the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. - The
orifice 210 may be installed in the case. Specifically, theorifice 210 is disposed under the top panel in a state in which theorifice 210 is connected to the front panel and the rear panel. - For example, the
orifice 210 may include adischarge part 211, aconnection part 215, and asuction part 213. - The
discharge part 211 guides air discharged from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 by theblower fan 220. - The
discharge part 211 defines theoutlet port 214. Specifically, thedischarge part 211 may have a shape having theoutlet port 214 defined therein. For example, thedischarge part 211 may be formed in a shape in which the front F and the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 are opened and thedischarge part 211 surrounds theblower fan 220 in a direction perpendicular to the axial direction of theblower apparatus 200. That is, thedischarge part 211 is formed approximately in a cylindrical shape. - The
discharge part 211 is located at the rear R of theblower fan 220 in the axial direction of theblower apparatus 200. - The center of the
discharge part 211 may be aligned with the shaft of theblower fan 220. - The sectional area of the
discharge part 211 is gradually increased from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. In addition, the width of thedischarge part 211 is also gradually increased. - Consequently, noise of air discharged by the
blower fan 220 is proportional to flow speed of air. The flow speed of the air is a value obtained by dividing the flow rate of air by a sectional area perpendicular to a flow direction of the air. - According to law of mass conservation, the flow rate of air is uniformly maintained irrespective of position in a flow direction (axial direction) of the air. When the sectional area of the
discharge part 211 is gradually increased, therefore, the flow speed of the air becomes slow. As a result, noise of the discharged air is reduced. - When the flow speed of the air is decreased, a difference in flow speed between the discharged air and external air at a
rear end 211A of thedischarge part 211 is reduced with the result that generation of an eddy in the air is restrained. As generation of an eddy in the air is restrained, efficiency of the outdoor unit is improved. - The sectional area means the area of a plane perpendicular to the axial direction.
- Specifically, the front end of the
discharge part 211 is connected to theconnection part 215 and therear end 211A of thedischarge part 211 is located more adjacent to the rear R in the axial direction than the rear end of theblower fan 220. Consequently, it is possible to sufficiently reduce the flow speed of the air having passed through theblower fan 220. - The front end of the
discharge part 211 means an end of thedischarge part 211 located at the front F in the axial direction and therear end 211A of thedischarge part 211 means an end of thedischarge part 211 located at the rear R in the axial direction. - That is, the
discharge part 211 may have a uniform height. The height of thedischarge part 211 means the distance from the front end of thedischarge part 211 to therear end 211A of thedischarge part 211. - The axial section of the
discharge part 211 may have a linear or curved shape. The axial section means the sectional area of a plane parallel to the axial direction. - A ratio of a width L2 of the
rear end 211A of thedischarge part 211 to a width L1 of theconnection part 215 may be 1.6:1 to 1.4:1. If the width L2 of therear end 211A of thedischarge part 211 is greater than 1.6 times the width L1 of theconnection part 215, the sectional area of thedischarge part 211 is sharply increased with the result that it is not possible to guide air flowing into thedischarge port 211. On the other hand, if the width L2 of therear end 211A of thedischarge part 211 is less than 1.4 times the width L1 of theconnection part 215, the sectional area of thedischarge part 211 is gently increased with the result that it is not possible to reduce the flow speed of the air discharged from thedischarge part 211. - In a case in which the sectional shape of the
discharge part 211 is circular, the width L2 of therear end 211A of thedischarge part 211 means the diameter of an internal space of thedischarge part 211. On the other hand, in a case in which the sectional shape of thedischarge part 211 is polygonal, the width L2 of therear end 211A of thedischarge part 211 means the average width of the internal space of thedischarge part 211. In addition, in a case in which the sectional shape of theconnection part 215 is circular, the width L1 of theconnection part 215 means the diameter of an internal space of theconnection part 215. - In addition, a difference between the width L2 of the
rear end 211A of thedischarge part 211 and the width L1 of theconnection part 215 may be 50 % to 100 % the width L1 of theconnection part 215. If the difference between the width L2 of therear end 211A of thedischarge part 211 and the width L1 of theconnection part 215 is greater than 100 % the width L1 of theconnection part 215, the sectional area of thedischarge part 211 is sharply increased with the result that it is not possible to guide air flowing into thedischarge port 211. On the other hand, if the difference between the width L2 of therear end 211A of thedischarge part 211 and the width L1 of theconnection part 215 is less than 50 % the width L1 of theconnection part 215, the sectional area of thedischarge part 211 is gently increased with the result that it is not possible to reduce the flow speed of the air discharged from thedischarge part 211. - The difference between the width L2 of the
rear end 211A of thedischarge part 211 and the width L1 of theconnection part 215 is a value obtained by subtracting the width L1 of theconnection part 215 from the width L2 of therear end 211A of thedischarge part 211. In addition, the width L1 of theconnection part 215 is equal to the width of the front end of thedischarge part 211. - In addition, the
rear end 211A of thedischarge part 211 may be located at the upper region of the case. Since the flow speed of the air discharged from thedischarge part 211 is higher than that of the air introduced into thedischarge part 211, noise is increased in thedischarge part 211. - In a case in which the
rear end 211A of thedischarge part 211 is located at the upper region of the case and the front F of theblower apparatus 200 in the axial direction of theblower apparatus 200 is aligned with a direction of gravity, therefore, the air is discharged from thedischarge part 211 toward the upper side of the case. - In general, the case has a predetermined height and, therefore, the
discharge part 211 is installed at the predetermined height from the ground. As a result, it is possible to reduce noise that people may hear in ear. - Particularly, in a case in which the height of the
rear end 211A of the discharge part 211 (which means the height from the ground) is designed to be equal to or greater than the average height of people, it is possible to further reduce noise of the air discharged from thedischarge part 211. - The sectional holes may be located under the
discharge part 211. Since the sectional holes are disposed at three sides of the case, the flow speed of the air suctioned through the sectional holes is reduced. Consequently, noise is low even when the sectional holes are disposed adjacent to ears of people. - The
suction part 213 guides air suctioned from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 by theblower fan 220. That is, thesuction part 213 increases the flow speed of the air suctioned by theblower fan 220. - The
suction part 213 defines theinlet port 212 of theorifice 210. Specifically, thesuction part 213 may have a shape having theinlet port 212 defined therein. For example, thesuction part 213 may be formed in a shape in which the front F and the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 are opened and thesuction part 213 surrounds theblower fan 220 in a direction perpendicular to the axial direction of theblower apparatus 200. That is, thesuction part 213 is formed approximately in a cylindrical shape. - The
suction part 213 is located at the front F of theblower fan 220 in the axial direction of theblower apparatus 200. That is, thesuction part 213 is located opposite to thedischarge part 211 via theblower fan 220. - The center of the
suction part 213 may be aligned with the shaft of theblower fan 220. - The sectional area of the
suction part 213 is gradually increased from the front F to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. In addition, the width of thesuction part 213 is also gradually increased. - Consequently, the flow speed of the air suctioned by the
blower fan 220 is increased. - The sectional area means the area of a plane perpendicular to the axial direction of the
blower apparatus 200. - Specifically, the rear end of the
suction part 213 is connected to theconnection part 215 and thefront end 213A of thesuction part 213 is located more adjacent to the front F of theblower apparatus 200 in the axial direction of theblower apparatus 200 than the front end of theblower fan 220. - Consequently, it is possible to sufficiently increase the flow speed of the air suctioned into the
blower fan 220. - The
front end 213A of thesuction part 213 means an end of thesuction part 213 located at the front F of theblower apparatus 200 in the axial direction of theblower apparatus 200 and the rear end of thesuction part 213 means an end of thesuction part 213 located at the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200. - That is, the
suction part 213 may have a uniform height. The height of thesuction part 213 means the distance from thefront end 213A of thesuction part 213 to the rear end of thesuction part 213. - The axial section of the
suction part 213 may have a linear or curved shape. The axial section means the sectional area of a plane parallel to the axial direction of theblower apparatus 200. - The

connection part 215 guides air suctioned from the front R to the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 by theblower fan 220. - Specifically, the
connection part 215 may be formed in a shape in which the front F and the rear R of theblower apparatus 200 in the axial direction of theblower apparatus 200 are opened and theconnection part 215 surrounds theblower fan 220 in a direction perpendicular to the axial direction of theblower apparatus 200. That is, theconnection part 215 is formed approximately in a cylindrical shape. - The

blower apparatus 200 with the above-stated construction according to the present invention and theair conditioner 1 having theblower apparatus 200 operate as follows. - First, the
suction motor 196 is driven to rotate thesuction fan 198. According to rotation of thesuction fan 198, external air is introduced into the outdoor unit through the suction holes. At this time, the external air is introduced into the outdoor unit in a horizontal direction. Since the external air is introduced into the outdoor unit from three sides in the horizontal direction, the flow speed of the air is low with the result that noise is also low. - The
outdoor heat exchanger 170, which surrounds thesuction fan 198 in the shape of ⊃, performs heat exchange between the introduced outdoor air and a refrigerant. - The outdoor air heat-exchanged with the refrigerant by the
outdoor heat exchanger 170 may be heated or cooled. Subsequently, themotor 230 of theblower apparatus 200 disposed above theoutdoor heat exchanger 170 is driven to rotate theblower fan 220. According to rotation of theblower fan 220, the heat-exchanged air flows upward. - The air heat-exchanged with the refrigerant is introduced into the
orifice 210. - Specifically, the air heat-exchanged with the refrigerant is introduced through the
inlet port 212 of thesuction part 213 of theorifice 210. At this time, the flow speed of the air is increased. - The air introduced into the
orifice 210 is rotated by theblower fan 220 and is blown in the axial direction of theblower apparatus 200. - The flow speed of the air blown by the
